If S/PDIF is a 75ohm coax what is the standard RG6 we use for SAT signals?
75 ohm as well. RG6 is a cable designed for higher frequencies than low level audio and video interconnects, but should still work. That's why they have quad shield RG-6 because at higher frequencies the cable starts acting like an antenna and starts radiating the signal out of the dielectric and shielding, I.e. skin effect. This is exactly why there is indeed some differences in cheap vs well designed and constructed cables like JPS Labs, Monster, etc. but of course they go overboard with their claims and prices and if you look hard enough will find affordable well made and designed cables elsewhere (monoprice, blue jeans, etc.)
